Optimal Temperature Control for the Latest R1 Generation

The Yamaha R1/R1M from model years 2017–2026 (RN49/RN65) are among the most technically advanced superbikes of all time. More power, more Electronics, more rev response – but also more heat generation. Under spirited road riding, trackdays, or in high ambient temperatures, the OEM cooling system quickly reaches its limits.

The H2O Performance water + oil cooler kit (EVO Series) is the high-end solution for maximum thermal stability. With an enlarged water cooler surface area and a high-efficiency oil cooler, it delivers substantial performance reserves, prevents heat soak, and ensures consistently strong engine performance.
